In manufacturing permanent magnets by filling insertion holes of a core with a magnet material, the density of the magnetic flux entering the magnet material can be restrained from being limited by the saturation magnetic flux density of the core. A guide member 40 is placed so as to face a core 22 in an axial direction Da. An orienting/magnetizing device 30 faces the core 22 and the guide member 40 in the radial direction and applies a magnetic field to the guide member 40 and the core 22 in the radial direction. Insertion holes 24 of the core 22 are filled with the magnet material through guide holes 42 of the guide member 40. The magnetic field is therefore applied from the orienting/magnetizing device 30 to the magnet material passing through the guide holes 42. |
